post 9. Se- 1 sprocket gears rollers are positioned at forty-five degrees,

idly secured to said channel bars. Mounted at vthe rearof the stenciling machine are two vertical parallel stencil guide plates 26, the inner surfaces of which are provided with continuous guide grooves or ways 27, in which the opposite ends of a stencil hanger or bracket rod 28, are 'slidably en gaged. The hanger 28, has one end of a The guide plates 26, are provided with vertical rows of openings near the inner margins thereof for rotatably receiving the trunnion ends of inking rollers 30, which are positioned in a vertical plane to co-act with the rear guide rollers 22. Also journaled in suitable openings near the lower ends of the guide plates 26, are the trunnions31 of an ink'supplying roller or cylinder 32, provided with a plurality of outlet openings 38, and a cylindrical inking pad 34. s5 Keyed or otherwise secured on the trunnions of the lowermost roller 30, are 35, positioned to co-act with the pin ends of the stencil hanger 28, when said hanger is automatically elevated from the full line position of Fig. 5 to the dotted sleeve 7. One end of a conductor wire 13, is

"stencil is in normal'position. The two solenoids are connected 1n series to thecircuit wires 11 and 15, as shown in the wiring diagram of Fig. 9.

The lowermost inking roller 30 and the lowermost rear roller 22, are adapted to be driven from any suitable source of power and act as feed rolls for feeding the stencil throughthe machine in a path following the guide grooves 27. Any suitable type of mechanism may be provided for drawing the ribbons 4, through the machine to permit stenciling thereof.-

The operation is as follows The stenciling machine is adapted to be used in combination with the erforating machine, as shown in Fig. 1. plurality of duplicate music roll ribbons 4, after being perforated by the perforating machine are conducted from said perforating machine to the lower portion of the intake or entrance end of the stenciling machine around the lowermost of the front guide rollers 24, and then upwardly to be successively runsingly over the respective entrance guide rollers 24; as shown in Fig. 7. .Each ribbon 4, passes 12: from its roller 24, horizontally across the machine from front to'rear upwardly around a rear roller 22, thenback into the machine downwardlyaround the respective diagonal roller 21, and then outwardlyover the re 13 the respective discharge rollers 23, the-various music roll ribbons 4, are conducted downwardly and all pass inwardly around the lowermost dischar e roller 23, out of the machine as shown in ig. 8.

Each music roll through the stenciling machine has its own respective set of guide rollers, each set comprising a diagonal roller 21, and a rear roller 22, disposed in the same horizontal plane,

and a discharge roller 23 and an entrance the same horibelow the plane of roller 24, both disposed in zontal plane parallel and the two rollers 21 and 22.

To properly stencil all of'the music roll ribbons 4, passing through; the machine it is necessary to start the feeding of the stencil 29, upwardly between the inking rollers 30 and the rear rollers 22, at'a predetermined time so that the names, signs or symbols will be stamped or printed on the various music roll ribbons 4, to exactly duplicate the stenciling on the master music roll ribbon 3. The master ribbon 3, automatically controls the starting of the stencil 29, into the stenciling machine. Normally the stencil 29, is in the position shown in Fig. 2, with, the ends of the hanger 28, resting on the upper ends of the solenoid cores 38. Asthe master ribbon 3, is conducted over the switch cylinder 7 and below the brush 10, the opening in the margin of said master ribbon is permitted to pass over said switch cylinder. When this occurs the brush 10, projects through said opening and closes contact with the switch cylinder 7 thereby closing the circuit to the two solenoids 37, which become energized and thereby cause the solenoid cores 38, to be automatically drawn inwardly. The operation of the solenoid cores 38, elevates the stencil hanger or bracket 28, into the dotted line position of Fig. 5, so that the pin ends of said hanger are engaged by the gears 35. The hanger 28, is thus carried upwardly between the lowermost inking roller 30, and the lowermost rear roller 22 with the hanger ends tracking in the guide grooves 27. As'soon as the opening in the master ribbon 3, passes the brush 10, the circuit to the solenoids is broken and th solenoid cores return to normal position. The,

co-acting rollers 22 and 30, however, now act to feed the stencil 29., upwardly therebe tween. The ink supply cylinder 32, is adapted to be rotated by any suitable means, thereby permitting ink to flow out of the apertures 33, to saturate the cylindrical inking pad 34. Ink is thus supplied to the inking rollers 30, which are adapted to supply ink to the stencil openings whereby the required words, signs, or symbols necessary for the proper playing of music rolls are stenciled on the various music roll ribbons 4, as they are conducted through the stenciling maribbon 4, conducted chine, of electric means for roll ribbons to be stenciled.

5. The

chine and brought into contact with the upwardly moving stencil 29. The stencil during its progress through themachine folguide grooves 27, and returns'to lows the normal by the music roll ribbons are fed intothe stenciling machine from the perforatingmachine.

It will thus be seen that one or a plurality ofmusic roll ribbons may be stenciled'at the same time to duplicate the stenciling of a master nusic roll which controls the operation of the electric mechanisms which are adapted to automaticallyact at a prede termined time to start thefeeding of a stencil into the stenciling machine.

The music roll ribbons 4, which are to be stenciled are drawn through circuitous paths through the machine over the respective guide rollers,
